of 2010, the congressional budget office was projecting out some savings because of the a.c.a. but they were figuring about 4% per capita growth, again as you pointed out this chart now shows we're down to 2%. so they've been revising their estimates over the last two years and the net savings, the recalculation just in the last two years has been hundreds of billions of dollars of lower expenditure than they had first thought was going to be the case. when you compare that magnitude of savings with, for example, raising the eligibility age to 67, i mean, they're dwarfed. it is really just a small portion of what efficiencies in the system are capable of producing. and the fact of the matter is that raising the eligibility age, i mean, there's no free lunch. the fact is that even though these are people that willing challenged in the private insurance market, 65 and 66 are still the healthiest population within the medicare pool. so the ones who remain in medicare, their part b premiums are going to go up and that's not just me saying it, it's the keiser family foundation who
